Acoustic Imaging Camera | 64 MEMS Microphones for Gas Leak & Partial Discharge Detection MPAI56

Product Description

The HIKMICRO MPAI56 Acoustic Imaging Camera is a professional-grade solution for gas leak detection and partial discharge inspection. Featuring 64 low-noise MEMS microphones, it provides precise, real-time sound source localization across an adjustable bandwidth range of 0–96 kHz.

With its 4.3" LCD touch screen, 16x digital zoom, and support for 8 acoustic imaging palettes, the MPAI56 makes inspections faster and easier. It intelligently identifies corona, floating, surface, and particle discharges, while also estimating leak rate, leak level, and leak cost. Compact and lightweight at just 940g, the camera is portable and rugged, with IP54 protection and a battery runtime of up to 3.5 hours.

Ideal for industrial maintenance, electrical inspections, and predictive reliability programs, the MPAI56 helps minimize downtime, improve safety, and reduce operating costs.
